Telnet weirdness
Hi,
I have two computers, one is running a slack 8.0 distro, the other I
am trying to migrate from slack to debian woody (Actually, Debian Woody
unofficial, purchased from Edmunds Enterprises). They are connected
by a single ethernet cable with a crossover network with static IP
addresses in /etc/hostname.
When both are running slackware, I can telnet between them by name
or ssh between them by name.
When one of them (named ragwind) is running debian, I can ping my other
computer (named bluemouth, which is always running the slack distro)
by name. i.e. "ping -c 1 bluemouth". But if I try 'telnet bluemouth',
telnet just hangs. On the other hand, 'telnet 192.168.0.1' works, where
192.168.0.1 is bluemouth's IP address. ssh does work by name, (i.e
ssh cpw@bluemouth. OK, so far, it's something I can live with, though
I'd really like to know why telnet bluemouth doesn't work (and better,
be able to fix it so it does.)
Going the other way is different. I can ping from bluemouth to my
debian machine (by name, 'ping ragwind') and I can mount a filesystem
from the debian machine on bluemouth ('mount -t nfs ragwind:...'),
but if I try to telnet, I get:
cpw@bluemouth:~$ telnet ragwind
Trying 192.168.0.2...
Connected to ragwind.loc.net.
Escape character is '^]'.
and that's it, it hangs until I quit out. ssh also hangs.
(However, ftp seems to work. At least I was able to do an 'ls' of a
directory from ftp.)
On the other hand, when I connect to my ISP with pppd, I can telnet in
to it with just plain 'telnet rahul.net' with no problem.
So mostly, I'd like to know why I cannot telnet in to the debian machine,
though I'd also like to know why I can only telnet to the slackware
using its naked IP address. Except for putting the IP addresses
in to /etc/hosts, I haven't done any special configuration. In order
to get the ethernet up and running I do the following (so far I do
this by hand, after the system is fully booted up)
insmod dmfe <to bring in the driver for the ethernet card>
ifconfig eth0 192.168.0.2
route add default eth0
That seems to be enough for slackware.
Thanks for any help
-Carl
